During a neighborhood baseball game in a vacant lot, a particularly wild hit sends a 0.148 kg baseball crashing through the pane of a second-floor window in a nearby building. The ball strikes the glass at 15.5 m/s, shatters the glass as it passes through, and leaves the window at 10.1 m/s with no change of direction. What is the direction of the impulse that the glass imparts to the baseball

Claire · Answer 1

mass of baseball, m = 0.148 kg

initial velocity, u = 15.5 m/s

final velocity, v = 10.1 m/s

Impulse is defined as the change in momentum of the body.

Impulse = change in momentum

I = m (v - u)

I = 0.148 (10.1 - 15.5)

I = - 0.8 Ns
